The PHENIX Collaboration has measured ϕ meson production in d+Au collisions at sNN=200 GeV using the dimuon and dielectron decay channels. The ϕ meson is measured in the forward (backward) d-going (Au-going) direction, 1.2<y<2.2 (−2.2<y<−1.2) in the transverse-momentum (pT) range from 1–7 GeV/c and at midrapidity |y|<0.35 in the pT range below 7 GeV/c. The ϕ meson invariant yields and nuclear-modification factors as a function of pT, rapidity, and centrality are reported. An enhancement of ϕ meson production is observed in the Au-going direction, while suppression is seen in the d-going direction, and no modification is observed at midrapidity relative to the yield in p+p collisions scaled by the number of binary collisions. Similar behavior was previously observed for inclusive charged hadrons and open heavy flavor, indicating similar cold-nuclear-matter effects.
